Lutung Kasarung is a Sundanese folktale from Indonesia. Set in the Pasir Batang Kingdom, it tells the tale of a magical lutung who helped a beautiful princess, Purbasari Ayuwangi, when her older sister attempted to rob her of her status as crown princess. The story is from an old Sundanese quatrain.

The Sundanese are an indigenous ethnic group native to the western region of Java island in Indonesia, primarily West Java. They number approximately 42 million and form Indonesia's second most populous ethnic group. They speak the Sundanese language, which is part of the Austronesian languages.
